Specification of Letters Patent.

Patented May 12, 1908.

Application filed April 7,1906, Serial No. 310,491. Renewed April 2,1903. Serial No. 424,771.

To all whom it may concern:

Be it known that I, Lnwrs A. llARKER. a resident of Cincinnati, in thecounty cl llamilton and State of Ohio, have invented certain new anduseful Improvements in Fire- Extinguishers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled. in the art to which it appertains tomake and use the same.

My invention relates to an improved lire extinguisher, the object of theinvention being to provide an improved construction of acid bottle cageand improved stopper for the bottle and mounting for the stopper, anddown yet limits such movement ant prevents possibility of its becomingmisplaced or lost, and the cage allows the bottle to be easil andquickly removed and replaced and is o extremely simple construction,cheap to manufacture, and securely holds the bottle in roper o )erativcposition.

Wit these 0 jects in view, the invention consists in certain novelfeatures of construction and combinations and arrangements of parts aswill be more fully hereinafter described and pointed out in the claims.

In the accompan 'ng drawings, Figure 1 is a view inverticasectionillustrating my improvements. Fig. 2 is a longitudinalsectional view through the-bottle and its cage, with the stopper shownin elevation. Fig. 3 is a transvcrsesectional view through the bottleand cage, and Fig. 4 is a view in section of the hose coupling.

1 represents the tank of a portable lire extin uisher, provided withscrew threaded nee at its upper end, closed by a cap 2, and

said tank is provided with the hose connection 3, for directing theextinguishing lluid and gas upon the fire. This tank 1, isada )ted tocontain a soda solution up to the esired level, preferably up to theflange or bead uniting the dome and body of the tank, and an acidsolution, such for instance, as sulfuric acid, for mixing with the sodasolution, when the tank is inverted, is contained in a bottle 4, andsupported by my improved cage 5, which. will now be described. The cage5, comprises a metal swin 6, and a ring 7. The swing 6 has a screw tireaded lug 8 at its upper end to screw into a threaded socket in thecenter of the cap or cover 2, and said swing is contracted at its upperportion the swing might plained.

to provide curved shoulders 9, and hold the bottle against slidinglongitudinally in the s\\'ing,when the tank is inverted. The par allclside bars of the cage are made with recessos 10, to receive and hold thering 7 and beveled enlargements i1 are provided on theuppcr sides of therecesses to permit the ring to he slid therein, and held in therecesses, and it will be seen that this ring 7 serves to hold the bottleagainst possibility of lateral movement and consequent escape from theswing. llowever, the ring '7 can be easily slid upward from therecesses, when the side bars are pressed inward, to permit the ring toride over shoulders 11, and when the ring is forced downward it willwhen engaging the beveled shoulders 11, compress the side bars and moveinto the recesses, the side bars springing outward and securing the ringin the recesses.

In the upper contracted portion of the swing, a cross pin 12 is secured,and my improved stopper 13 has an elongated slot 14:

all possibility of the stopper becoming displaced or lost.

The stopper is preferably cast of commereial lead, cored to form theslot 14, and has an elongated tongue at its lower end projecting downthe neck of the bottle to hold the stopper against pivotal movement onthe pin, but compel the same to fall back to closing position when thetank is lighted. The stop per might, of course be com osed of othermaterial, and mi ht be alterer in shape, and

he made of various metals, although I prefer to'construct the same ofcast brass. 1

By constructing my improvements as above explained, a cage of extremelysimple construction is secured, which permits of easy and quick removaland replacing of the bottle whenever desired, and the stopper while freeto move up and down to release the contents'o'f the bottle, suchmovement is limited and is always maintained in its proper operativeposition. i

The hose 21' is connected to a tube 15 by an improved coupling whichwill now be ex- The end ol the tube 15 is externally screw threaded andinternally bored to form a narrow bearing face 16. 17 represents theceuelin ceded nipple L. to T0"1Y made 1 provides 21502111 for gainsiwhic the end of tube 1 cfi'ccf- I ing a perfectly tight joint, v rcnmnnf this grooved seat for 11-? 1 her 20 and mede 1n Lhe ere! form and fmy invention and hence myself to the pre(. sider m seif at 1 cmnges andeltmmiei-ls F eke spi ib and scope of my Havmg fully described my: 1claim as new and desire o secure Patent, is:
